Hello aspirant. With 141, your chances of getting a seat in private or deemed university are quite low, despite having reservation. However, you can wait till mop up round and apply in the following colleges-

1. SRM Medical College and Hospital

2. Saveetha Medical College

3. Sree Balaji Medical college and hospital

4. Sri Ramachandra Institute of Higher education and research

You can also wait till stray vacancy round where you have chances to get admission in the above mentioned deemed medical college. You may want to keep visiting mcc site for updates on mop up and stray vacancy round. Hope it helps!
